Root Cause

Same Domain Origin Policy was not satisfied when testing.  The purpose of getGadgetData is to get content from the PRPC display area for use in the main top level application.  With out Same Domain Origin Policy met the outer application can not communicate with the PRPC generated iframe


Always test mashup functionality in an environment that satisfies Same Domain Origin Policy.
